This is just based on my personal experience, so please take it with a grain of salt.

Rather than gaining ground from the wider population, I see the recent rise in Linux usage as coming from a pool of "interested users" who have in one way or the other, had some prior exposure and thus interest in Linux. These people have already been interested in making the jump, but have been held back in one way or the other.

This shouldn't be taken as discounting the recent advances amongst Linux distributions, however. Personally, the reason why I've made the jump is two-fold: dissatisfaction with Windows, and the advances in Linux itself that have made the jump far less intimidating than ever before. Not being a gamer, however, advances in Proton was only seen as a bonus, though a very welcome one.

Only one other person in my current friend group daily-drive Linux, and like me, they already have had experience with it beforehand. There are some other people I know of who have used Linux, but still, they all have had prior experience from school or work. For everyone else I‌ know of, if they've even heard of Linux, they think of it as "for advanced users" and as one contact put it "way above my pay grade". Unfortunately, in so far as personal experience goes, I don't have confidence Linux will be shedding that image anytime soon.

As for the Steam Deck, I am guessing it'd be similar (with a lot of caveats) to how people see Android. It'd be seen as a separate thing, and not occupy the same mental space as "desktop Linux". For one, it being a hand-held system will reinforce that difference, and people aren't as willing to tinker about with their handhelds as people are with their desktop systems. Steam Deck's OS might as well be BSD or even Temple OS as far as the ordinary user is concerned. I am hoping I am wrong here, however, as interoperability might make a difference here: if people can install and use their desktop programs to their Steam Decks in as much the same ease as installing an Android app in their phones, then perhaps the choice of OS here will make an impression on the users and not just the tinkerers.

Despite saying all that, however, I still think Linux is undergoing a renaissance. There's quite a lot of improvements going on even as we speak. Usability, in a very general sense, like being able to daily-drive Linux without being hampered by a lot of issues, is way better than it was when I first used a Linux machine in a school computer laboratory close to twenty years ago. Advances like this is starting to pull people who are curious, interested, and already leaning towards making the jump—and if this trend continues, will lead more people into using Linux, leading to more people contributing towards advances, and so on.

No, I think the success comes from Linux becoming normalized in devices like Android and the Steam Deck. We'll see how it shakes out.

The Steam Deck has been a gamechanger, pun intended :)

I've broken my Nvidia driver 4x this week and I wouldn't have it any other way (not /s)

Nothing else compares to the flexibility of linux and if I need a kernel-level anti cheat I do it on a separate drive entirely (which can't see my linux BTFS drive at all)

There sure is new comers thanks to the enhancement of graphic environment and gaming. But this is still very marginal, and there is some good reasons.

If we want to promote linux and FOSS we couldn't only rely on use-cases and good-will of people, we need to find structures that make people use mac and windows. FOSS movement make some interesting stuff about the education system, and the institution use of windows, which are a lot more impact on the OS we are using than the qualities of such systems. But the so-called "politically neutral" forbade us to prevent this situation to repeat itself. Microsoft works on daily bases with tremendous resources (not only monetary). People who are making this decisions have some carrer interests that is not align on those of the masses.

Free-software without anti-capitalism is only open-source, sry

That not a moral state; some capitalist on corporation help us a lot. The main reason for the linux promotion is the choice of Valve, but because that choice is not profitable (in a capitalist way), we should consider it as the exception.

I'm not saying that it's helpless. It's quite the opposite : I'm saying that if we want to have a massive action, we have to take the power were it is.

Removed by mod

I think that happened a few years after Ubuntu came out

Should have went with L I U X
